Telemetry Test

Each small box on the monitoring EKG paper is how man seconds? - answer-0.04 seconds Paroxysmal means? - answer-sudden onset and sudden termination Unique waveform characteristics of: Sinus Arrythmia - answer-Regularly Irregular Sinus rhythm Unique waveform characteristics of: Atrial Fib - answer-irregularly irregular with no p wave Unique waveform characteristics of: Atrial Flutter - answer-prominent f waves/saw tooth pattern atrial kick is responsible for how much cardiac output? - answer-20-30% cardiac output PVC - answer-premature ventricular contraction PAC - answer-premature atrial contraction PJC - answer-premature junctional contraction Unique waveform characteristics of: junctional complexes - answer-may have no p waves, may have inverted or negative p waves, and have a PRI of 0.12 (short) Hallmark signs of a PVC - answer-wide and bizarre QRS complex, originates in ventricle, and usually has a compensatory pause bigeminy - answer-Ectopic beat every other beat trigeminy - answer-ectopic beat every third beat quadgeminy - answer-ectopic beat every fourth beat PVCs are frequently caused by what? - answer-Hypokalemia aberrant/aberrancy refers to what - answer-refers to abnormal conduction through the ventricles (cell to cell) resulting in wide complexes Unique waveform characteristics of: VTach - answer-usually has a regular rhythm Which lead is best for measuring waveforms for rhythm interpretation? - answer-Lead II Normal p waves - answer-should be upright, best seen in Lead II truest picture of ventricular activity is in which lead - answer-V lead Assessing new onset ST elevation - answer--presence of pain, SOB, or discomfort -check for lead placement accuracy -position patient in supine position with HOB up 30" and reassess ST -12 lead EKG and call MD
